nsight.nvim

NVIDIA Nsight Integrated tools for Neovim.

Overview

nsight.nvim is a Neovim plugin that provides seamless integration with NVIDIA Nsight profiling tools. It allows you to manage CUDA profiling sessions, run various NVIDIA tools, and analyze profiling results without leaving your editor.

Requirements

Neovim (v0.9.0 or higher)
NVIDIA CUDA Toolkit:
- nvcc: NVIDIA CUDA Compiler
- nvvp: NVIDIA Visual Profiler
- ncu: NVIDIA Nsight Compute
- nsys: NVIDIA Nsight Systems

Installation

Using lazy.nvim

{
    "Jorgedavyd/nsight.nvim",
    config = function()
        require("nsight").setup({
            -- Your configuration here
        })
    end,
}

Using packer.nvim

use {
    "Jorgedavyd/nsight.nvim",
    config = function()
        require("nsight").setup({
            -- Your configuration here
        })
    end
}

Using vim-plug

Plug 'Jorgedavyd/nsight.nvim'

" After installation, in your init.lua:
" lua require('nsight').setup({})

Using dein.vim

call dein#add('Jorgedavyd/nsight.nvim')

" After installation, in your init.lua:
" lua require('nsight').setup({})

Configuration

Default Configuration

require("nsight").setup({
    session = {
        window = {
            title = "Nsight Session",
            title_pos = "left",
            width_in_columns = 12,
            height_in_lines = 8,
            style = "minimal",
            border = "single"
        },
        keymaps = function(bufnr)
            -- Define your keymaps here
        end,
        resolve_triggers = {}
    },
    extensions = {
        telescope = {},
        sqlite = {},
        cli = {}
    }
})

Functionalities

Main Features

Session Management: Create and manage CUDA profiling sessions
File Integration: Add CUDA source files to your profiling session
Tool Integration: Run NVIDIA profiling tools directly from Neovim
Report Analysis: View and analyze profiling reports
Project Management: Organize profiling experiments per project

Commands

Command	Description
`NsightActivate`	Activate the profiling session
`NsightDeactivate`	Deactivate the profiling session
`NsightToggle`	Toggle the profiling session
`Nvcc`	Run NVIDIA CUDA Compiler
`Ncu`	Run NVIDIA Nsight Compute
`Nvvp`	Run NVIDIA Visual Profiler
`Nsys`	Run NVIDIA Nsight Systems
`NsysUi`	Open NVIDIA Nsight Systems UI
`NcuUi`	Open NVIDIA Nsight Compute UI

API Functions

Function	Description
`toggle_include()`	Include the current buffer's filepath in the session
`toggle_view()`	Open the interactive session window

Telescope Integration

The plugin integrates with Telescope for enhanced file selection and report browsing:

-- Add to your telescope configuration
telescope.load_extension('nsight')

-- Usage
:Telescope nsight file_add_cuda    -- Find and add CUDA files to session
:Telescope nsight nsys_open_report -- Open Nsight Systems reports
:Telescope nsight ncu_open_report  -- Open Nsight Compute reports

Project Structure

nsight.nvim creates a .nsight.nvim directory in your project root to store profiling experiments and configurations. Experiments are organized based on the files being profiled.

Experiment Structure

.nsight.nvim/
├── .config                    # Session configuration
└── experiments/
    └── file1_file2/           # Experiment for specific files
        ├── report1/           # Profiling report
        ├── report2/
        └── .history           # Experiment history

Examples

Basic Usage

-- In your init.lua
require("nsight").setup()

-- In Neovim
:NsightToggle           -- Open the profiler window
-- Add CUDA files to the session
:NsightDeactivate       -- Save the session
:Nvcc -o output main.cu       -- Compile a CUDA file
:Nsys profile ./output        -- Profile the compiled binary
:Telescope nsight nsys_open_report -- View the report

Custom Keymaps

require("nsight").setup({
    session = {
        keymaps = function(bufnr)
            -- Define keymaps for the profiler buffer
            vim.api.nvim_buf_set_keymap(bufnr, 'n', '<CR>',
                "<cmd>lua require('nsight').toggle_include()<CR>",
                { noremap = true, silent = true })

            vim.api.nvim_buf_set_keymap(bufnr, 'n', 'q',
                "<cmd>lua require('nsight.ui').close_menu()<CR>",
                { noremap = true, silent = true })
        end
    }
})
